Hi,
I'm thinking about improving my current dust collection in my workshop. I have 50mm pipes running through the shop connected to a central vacuum. Currently, the vacuum automatically turns on when a connected machine is turned on (via this relais (https://www.schalk.de/messrelais/articles/imr-3.html)).
It works well, but I'd like to be able to manually turn on/off and adjust the power of the vacuum using a remote. The workshop is about 10x5m².
So my rough idea is the following: I'd use a Moteino (trace antenna) with RFM69CW for the remote. I'd add some buttons to turn on/off and a potentiometer to adjust the power. To control the vacuum I'm thinking about using a Controllino mini (https://www.controllino.biz/controllino-mini/), because it already has functionality to switch 230V. I would connect a RFM69CW (https://lowpowerlab.com/shop/product/156) to the Controllino to give it RF capabilities. I would use these products to control power for the vacuum turbine: Power control (https://www.kemo-electronic.de/en/Light-Sound/Effects/Modules/M028N-Power-control-110-240-V-AC-4000-VA.php) and Pulse converter (https://www.kemo-electronic.de/en/Transformer-Dimmer/Converter/M150-DC-pulse-converter.php)
I'm a beginner with RF, but have some experience with arduino (mainly LED projects). I'd like to do this with ready-made boards, I have no experience with making my own boards. So here are my questions:
- can I use the RFM69CW board to add RF capabilities to the Controllino? Do I need an antenna for it?
- can you recommend an easy way to supply the remote with power? I'm thinking a board which provides power via LiPo battery and also provides charging
- any other ideas, improvements are welcome
Thank you,
Johannes
EDIT: I did some more reading and I'm now confident that I should be able to achieve what I want. I order a Moteino (trace antenna) with HCW and another HCW. I realized the Moteino ships with an antenna. Have to figure out power supply now...
